Synthesis of encapsulated nanofertilizer from biogas plant digestate
Biogas digestate, though nutrient-rich, is underutilized due to its unpleasant odor and limited efficacy as fertilizer. This study synthesized an encapsulated nanofertilizer (ENF) using polyurethane (PU) to enhance nutrient release control. Nitrate release studies showed that ENF delayed significant nutrient release to 10.57 days, aligning with controlled-release fertilizer standards by achieving a maximum of 65 % nutrient release over 30 days. Nutrient release kinetics fitted the Korsmeyer-Peppas model (R2 = 0.9984), confirming diffusion-controlled Fickian release and a matrix-based system. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) analysis confirmed the matrix structure, while Fourier Transform Infrared Spectroscopy (FTIR) verified the successful synthesis of PU coating. These findings suggest that encapsulated nanofertilizer improves nutrient release profiles, offering a sustainable solution for digestate valorization.
